An object of the invention resides in the novel manner of shaping andconstructing fitting connection witha handle unit and a removablesleeve.

- A feature of the invention resides in the form of interconnectionbetween the casing members, the brake-mechanism, the reel unit, thesleeve and the handle unit which enables by a simple operation theinterconnection of the brake mechanism with one'of the housing members,the quick placement of the reel 5 unit in position with the brakemechanism,

the quick interconnection of the casing members and the locking of thecasing members in position by the forcing of the handle unit and thesleeves into attaching connection 3 with the casing members.

Another featureof the invention resides in the providing of the casingmembers with companion flanges and neck sections so that the membersmaybe readily forced into interlocking engagement with each other and heldin such engagement by' a sleeve and tubular handle unit which areslipped over the neck sections which not only establishes a rigidconnection between the sleeve, handle unit, and the casing members butpositively locks the latterefrom moving in..a directionthat woulddisconnect the same.

Besides the above my invention is distinguished inthe formation of the:component parts of metal stampings that ,are s'odesigned they arecapable of being connected to each other by a chain system ofproduction.-

With these and other objects in View the invention will be betterunderstood from the' following detailed description taken in connectionwith the accompanying drawings wherein--' Y i Figure 1 is a plan view ofthe handle structure.

Figure 2 is a I Figure 3 is a side elevation partially disconnected.

Figure 4 is a perspective view of one of the casing members;

- Figure 5 is a cross sectional view of a (for- 50 7 tion of the casingmembers disconnecte Figure 6 is an enlarged detailed sectionalviewthrough the bearing and associated parts. I

Again referring to the drawings illustrating one of the manyconstructions of my invention, the numerals 1 and 2 designate thecompanion members of the'casing 3 of the handle structure. In theparticular showing the members are illustrated as metal stampings whichenablsthe production of the members at a low cost. In'the stamping ofthe members the bodies4' are provided as well as the neck sections 5,there being companion flanges 6 .formed along the abutting edge portionsof the bodies so that thebodie's may be brought into interlockingconnec-' tion with each other. In a particular showing one of the-flanges 6 is oifset from the 30 body 4 whereas the other flange is inalign- 'ment with the, body 4 so that when the bodies are broughttogether the casing '3 will have a smooth exterior surface. One of theneck sections is minus flanges so that the edge 35 portion 7 may bebrought into flat abutting relation with each other to eliminate projections interiorly of the neck. The member 1 in the stamping thereof isformed with a depression 8 and a hole 9 centrally of the depression forthe reception of a bearlng 10. I I

This bearing 10.is further provided with a plate 11 received within thedepression 8 and further provided with a hub- 12 passed 3 through thehole 9 so as to occupy, aposition l of the casing. This bearing 10 may Iinteriorlg be locke in position inany desired manner such as by spotweldingor insertable fasteningdevices so as to secure the same inposition 1 longitudinalsectional View. 55

' '9 inated from thlsspecification a detailed idein conjunction with theparts of a brake mechanism hereinafter described.

The brake mechanism illustrated is practically identical with that shownin the above 5 mentioned co-pending application with the exception thatthe'bearing ring 14 is directly secured to the plate 11 through the wallof the casing by means of the screws 15. The brake ring 16 that ismovably mounted on the bearing ring 14 is provided with recesses 17 withwhich interconnects the lugs 18 projecting from. the reel unit 19.Thisreel ,unlted designed along the lines of the unit shown in my abovementioned copend-ing application is mounted on an axle 20 that issecured to the hub 12.

A screw 21 passing through the casing member and engaging the end of theaxle 20 not only supports the axle but provides a rigid connectionbetween the casing members at a central point.

As far as I have proceeded it will be appreciated that the bearing maybe readily slipped into place and the brake assembled on 12 and broughtinto interlocking engagement with the brake ring 16 through thedisposing of the lugs 18 within the recesses 17. After this hasbeenacc'omplished the inserting of the screw 21 provides a-secondbearing support for-the axle and besides draws the component partstogether with the flanges of the casing members in proper-interlockingconncctionj .For the purpose of providing a more rigid connection forthe casing members, and also decrease the cost of assemblage operation,I provide a rigid connection between the handle proper and the casingand between the casing and a socket structure and to accomplish this Itake advantage of the arrangement of and the abutting relation providedbetween the .neck sections.

, The handle unit 22 is formedfrom a tube and provided with a 'hand grip.23 with the outerend portion closed by the lug 24. The inner endportion of the .han le 1s slipped over and has a snug fit with a set ofthe companion neck sections 5 thereby locking the neck sections togetherand the handle inengagement with the casing. To provide a more positiveconnection, the handle as well as the neck sections may be upset at thepoint 25 or ihe handle may be spot welded to the neck sec- Theremaini'ngset of neck sections are positively held in abutting .relationfwith eachother by interengagement therewith of the sleeve 26101311111 one of themembers of the socket unit 29. 7 he neck sections 5 that I associatedwith the sleeve 26 are formed with a head 28 which provides an abutmentfor the socket 29 when the same is forced into place. For the pur' useof clarity I have elimthe hub and the reel unit slipped on to the hubtities of the component parts may be assembled at various points in anassemblage lane. That is to say, a group of the casing members 1 may bearranged at the start of. the production system, arranging in aprogressive line groups of associated parts terminating with a group ofsockets 29. It will be appreciated it is a Very simple operation toassemble the various parts due to the fact thatthe bearing 10 maybe veryquickly'slipped into position within the depression 8 and locked in saidposition by the screws 15 that secure the hearing ring 14. The brakering 16 can be very easily mounted upon the bearing ring and then theaxle 20 may be secured to the hub 12. A further step in the assemblingoperation relates to slipping onto the hubl2, the reel unit 19, bringingthe lugs 18 thereof into 1 interlocking connection with the recesses 17inthe brake ring for providing a positive connection between the brakering and the f reel unit. As a next step in the assemblage of the partsthe casing unit 2 is forced into interfitting connection with the casingunit 1 through the interrelation of the flanges 6; When this has beenaccomplished the screw 21 is in mounted position which looks theheretofore described parts in assemblage relation.

As a final operation the handle unit 22 is slipped onto the necksections and locked thereto by upsetting atthe point 25. Sleeve 26 isthen forced onto the remaining set of 1 neck sections and the socket 29forcedinto position in abutting relation with the bead 28.

It will now be apparent that I provide a very substantial type of handlestructure for vacuum cleaners mcorporating an automatic cord take-updevice in which the various parts are so designed that they may beeconomically produced and assembled at a minimum cost. Of course it isto be understood that'the de sign of the component parts may be changedand the mode of assemblage ma be varied without departing from thespirlt of the invention and therefore I do not desire to be limited inprotection in any manner whatsoever except as set forth in the following'1 claims.

What I claim is: v

hand.

ed by one of the casing members, an axle se cured to the remainingcasing member, and

also secured to said bearing thereby forming an interconnection betweenthe central portions of the said casingmembers, and-a reel bearing.

2. A vacuum cleaner handle structure comprising companion casing membershaving marginal flanges arranged in overlapping relation with each otherand further provided with two sets of neck sections extendinfiefromopposite points from the casing mem rs, a
